A video encoding/decoding method and apparatus is disclosed that can efficiently compress/decompress motion vectors in a video codec including a hierarchical temporal level decomposition process. The video encoding method including a hierarchical temporal level decomposition process involves obtaining a predicted motion vector of a second frame, which exists at a present temporal level, from a first motion vector of a first frame that exists at a lower temporal level; obtaining a second motion vector of the second frame by performing a motion estimation in a predetermined motion search area using the predicted motion vector as a start point; and encoding the second frame using the obtained second motion vector. |
